If your regulator is getting hot enough to cause Titanium to burst into flames, you've got more problems than that
200 degrees c, not that hot in fire terms.
contaminants that may be present that ignite can easily achieve this.

if you use your reg with standard compressed air, it must be recleaned before use with nitrox because compressed air contains traces of hydrocarbons and potentially flammible residues which are incompatibile with enriched oxygen use.

I have a difficult time understanding the logic of this statement. Does the manual reason that EAN mixtures are "pure", while compressed air has "traces off ... potentially flammible residues". This goes in the face of my understanding that EAN fill ups use compressed air with a 'charge' or blend of 100% Oxygen. The point being, the majority of the mixed EAN breathing gas comes from a compressor - does it not? Ergo, the EAN mixture contains the same 'contaminants" as compressed air. Why should cleaning a regulator for Nitrox use after using compressed air be a factor?
NITROX T2 ONLY...generally it's 'safe' to use recreational Nitrox mixes (up to EAN 40) with TI regs.....I've got an Atomic T2 that's OK with that......the big issue is the purity of the fills and if you switch back and forth between 'air' and NITROX. If you get your fills at various places (locally and/or on an overseas dive trip....third world location/primitive-poor conditions/too cheap to keep filters swapped out often enough) you increase the odds of getting fills from dirty/oily compressors, contaminating the 1st-stage...then if later on you use that TI reg with a high O2 %, with 3000 + PSI flowing into the 1st-stage, you might cause a TI fire......bad news! ......just keep the 'mix' below EAN40.....make sure all O-rings are swapped out with Nitrox compatable ones.
NITROX T2 ONLY
DO NOT switch between EAN and compressed air ........UNLESS......... it meets the more strigent purity standards for oxygen compatible air (OCA) as defined by ANDI/IANTD.
